Description

Lighting device for automatic switching between visible light source and infrared light source

Technical Field

The present description relates to a lighting device, and more particularly to a lighting device for automatically switching between a visible light source and an Infrared (IR) light source.

Background

An illumination device, such as a flash, is a device for generating regular flashes of light that can supplement the camera with light. In the traffic monitoring system, a flash may be installed at a fork, school zone, residential zone, and the like of a road to work together with a camera for capturing high-quality images or high-quality videos. Existing flashlights typically emit white light as supplemental light. Although white light can meet the light supplement requirement, the white light may cause light pollution to drivers and nearby residents. It is therefore desirable to provide a lighting device for selectively supplementing light to reduce light pollution.

Some embodiments of the present description relate to systems and methods of lighting devices. The lighting device may be automatically switched between a visible light source and an infrared light source. In some embodiments of the present description, a lighting device may include a switching device and one or more light sources. Specifically, in some embodiments, only one light source is used. The on-off of the switch device can be controlled, so that the aim of automatically switching between two lights is fulfilled. In some embodiments, the switching device may be an infrared filter, and the switching device may be used to switch between the visible light source and the infrared light source depending on the actual situation. The switching device may be periodically turned on or off based on information according to the detected environmental conditions. For example, in bright environments (e.g., during the day), the light intensity may be large enough such that the switching device (e.g., an infrared filter) is in a non-operational state. The illumination device may emit visible light when the switching device (e.g., infrared filter) is in a non-operational state. Conversely, when the light intensity is weak, the illumination device (e.g., an infrared filter) may emit infrared light to filter out visible light in a dark environment (e.g., at night or in a backlight condition) when the switching device is in an operating state. The switching means may be controlled by logic associated with the environmental sensor and/or the image capture means. For example, the switching device may be directly or indirectly controlled by an exposure time controller that controls the exposure time of the image capturing device to obtain a better-performing image from the image capturing device. The switching device may further control the light sources of the lighting device to emit different lights. The different light emitted from the illumination device may provide supplemental light for the lens and/or the sensor of the image acquisition device. For example, when the illumination device emits visible light for the image acquisition device, the image acquisition device may acquire an image based on the visible light. The acquired image may include color information. When the illumination device emits infrared light for the image acquisition device, the image acquisition device may acquire an image using the infrared light. The acquired image may include luminance information. A processor of the image acquisition system may process the image including the color information and the brightness information to generate an enhanced image for better effect. The image acquisition system comprises an illuminating device, an image acquisition device and a processor, and can acquire images under different lighting and acquire better images.

Fig. 1 is a schematic diagram illustrating an exemplary image acquisition system 100, according to some embodiments of the present description. In some embodiments, the image acquisition system 100 may be used in electronic devices that require acquisition of images or video, such as digital cameras, video cameras, smart phones, surveillance devices, and the like. As shown in fig. 1, the image acquisition system 100 may include an image acquisition apparatus 110, a lighting apparatus 120, a processor 130, a network 140, and a storage device 150.

Image capture device 110 may be configured to capture images or videos. The image or video may be two-dimensional (2D) or three-dimensional (3D). In some embodiments, image capture device 110 may comprise a digital camera. The digital cameras may include 2D video cameras, 3D video cameras, panoramic cameras, Virtual Reality (VR) cameras, webcams, point-of-care video cameras, surveillance cameras, and the like, or any combination thereof. In some embodiments, image acquisition device 110 may include a stereo camera. The stereo camera may include a binocular vision device or a multi-function video camera. In some embodiments, the image acquisition apparatus 110 may be added to or part of a medical imaging device, a night vision device, a radar device, a sonar device, an electronic eye, a camera, a thermal imaging device, a smartphone, a tablet, a laptop, a wearable device (e.g., 3D glasses), an eye of a robot, a vehicle tachograph, an unmanned device (e.g., an Unmanned Aerial Vehicle (UAV), an unmanned automobile, etc.), a video game console, etc., or any combination thereof.

In some embodiments, image acquisition device 110 may include one or more lenses, sensors, exposure time controllers, amplifiers, and analog-to-digital (A/D) converters.

The lens may be an optical or digital device that focuses light (e.g., visible and/or infrared light) by refraction to form an image. A shot may be configured to ingest a scene it faces. The lens may include an iris mechanism that adjusts the lens iris. The aperture of the lens may refer to the size of the light that passes through the aperture to the sensor. The larger the aperture, the more light is absorbed by the lens and the brighter the image captured by the image capture device 110. The aperture may be adjusted to adjust the amount of light passing through the lens. The focal length of one or more lenses may be fixed or adjustable to adjust the coverage of the image capture device 110. The lens may be controlled by a controller. For example, in some embodiments, different lenses or configurations of lenses may be controlled by a controller according to the on-off condition of the light source. In some embodiments, the illumination device may emit visible light when the switching device (e.g., infrared filter) is in a non-operational state, and thus, a particular set of lenses or lens structures may be used to capture visible light under more appropriate conditions. Conversely, the illumination device (e.g., an infrared filter) may emit infrared light when the switching device is in an operating state, thereby filtering out visible light in a dark environment (e.g., at night or in backlight conditions) when the light intensity is weak, and another set of lenses or lens structures may be used to capture infrared light under more appropriate conditions.

The sensor may detect and transmit light (e.g., visible and/or infrared light) captured by the lens as an electronic signal. The sensor may include a Charge Coupled Device (CCD) and a Complementary Metal Oxide Semiconductor (CMOS). In some embodiments, different kinds of sensors may be selected depending on different switching conditions of the light source. The sensors may be controlled by a logic controller associated with the switching device. For example, the sensor may be controlled directly or indirectly by a controller connected to the switching device. In some embodiments, the illumination device may emit visible light when the switching device (e.g., an infrared filter) is in an inactive state, and thus, a particular set of sensors or sensor structures may be used to detect and transmit light received by the lens into an electronic signal under more appropriate conditions. Conversely, the illumination means (e.g. an infrared filter) may emit infrared light when the switching means is in the active state, thereby filtering out visible light in dark environments (e.g. at night or under backlit conditions) when the light intensity is weak, and another set of sensors or sensor structures may be used to detect and transmit the light picked up by the lens into an electronic signal under more suitable conditions.

The exposure time controller may be configured to control the exposure time of the image capturing device 110. The exposure time may refer to the length of time when a sensor within image capture device 110 generates an electrical signal. In some embodiments, the exposure time controller may be a shutter device (e.g., a mechanical shutter) configured to open to allow light to pass through one or more lenses to the sensor, thereby causing the sensor to generate an electrical signal when an image is acquired. The shutter device may be controlled manually or automatically. The interval from the opening to the closing of the shutter device to photograph a scene may be an exposure time (also referred to as a shutter speed). In some embodiments, in the absence of electricity, the sensor does not generate an electrical signal even if light reaches the sensor. The exposure time controller may be an electronic shutter for controlling the length of time when the sensor is powered (also referred to as the exposure time or shutter speed). The longer the exposure time, the more electrical signals the sensor generates and thus the brighter the image acquired by the image acquisition device 110. The exposure time controller may be configured to be connected to the light source. For example, the exposure time controller may directly or indirectly control the switching device, and the switching device may further switch the operating state or the non-operating state to control the light source to emit different light. The operating state or the off state of the switching device may be controlled according to the exposure time controlled by the exposure time controller.

The amplifier may be configured to amplify the electrical signal generated by the sensor. The amplification of the electrical signal produced by the sensor may be a gain level. The higher the gain level, the brighter the image acquired by image acquisition device 110 (the higher the gain level the more noise is a side effect). In some embodiments, different kinds of amplifiers may be selected according to different switching conditions of the light source. The amplifier may be controlled by a logic controller associated with the switching device. For example, the amplifier may be controlled directly or indirectly by a controller connected to the switching device. In some embodiments, the illumination device may emit visible light when the switching device (e.g., infrared filter) is in a non-operational state, and thus a particular set of amplifiers or amplifier structures may be used to amplify the electrical signal generated by the sensor under more appropriate conditions. Conversely, the illumination device (e.g., an infrared filter) may emit infrared light when the switching device is in an operational state, thereby filtering out visible light in a dark environment (e.g., at night or in backlit conditions) when the light intensity is weak, and another set of amplifiers or amplifier structures may be used to amplify the electrical signal generated by the sensor under more appropriate conditions.

The a/D converter may be configured to convert the amplified electrical signal from the amplifier into a digital signal. The digital signals may be converted to an image processor (e.g., processor 130 or a processor in image acquisition device 110) to generate an image.

In some embodiments, one or more components of the image acquisition apparatus 110 (e.g., the image acquisition apparatus 110, the lighting apparatus 120, the processor 130, or the storage device 150) may communicate with each other via the network 140. For example, the lighting device 120 may send a switching signal to the processor 130 via the network 140. The switch signal may indicate which light (e.g., visible light, infrared light) is emitted by the lighting device 120. Image capture device 110 may send the captured image to processor 130 via network 140. The processor 130 may receive the switching signal and process the image acquired based on the switching signal, and transmit the processing result (e.g., the enhanced image) to the storage device 150 via the network 140.

In some embodiments, when image acquisition device 110 is in a bright environment, a filter may be added to image acquisition device 110 that prevents the sensor from receiving infrared light (e.g., infrared light from objects around image acquisition device 110), which ensures the color of the image acquired in the bright environment. When the image acquisition device 110 operates in a dark environment, the optical filter may be removed, which allows the sensor to receive infrared light from the illumination device 120 to increase the brightness of an image acquired in the dark environment.

In some embodiments, the image acquisition device 110 may include a double pass filter that allows infrared light and visible light having a particular wavelength (e.g., 840-860nm) to pass through. When the image acquisition apparatus 110 is in a bright environment, the effect of infrared light on the color of an image acquired in a bright environment may be reduced because the sensor is allowed to receive infrared light of a particular wavelength rather than all infrared light (e.g., infrared light having a wavelength of 700nm-1 mm). The brightness of an image acquired in a dark environment may be increased based on infrared light having a specific wavelength. The use of a double-pass filter in the image acquisition apparatus 110 may avoid time consumption caused by switching filters, as compared to switching filters between dark and bright environments.

The illumination device 120 may emit light (e.g., a flash of light) to supplement the light for the image acquisition device 110. For example, in bright environments (e.g., during the day), the lighting device 120 may emit visible light. In dark environments (e.g., at night or in backlit conditions), the illumination device 120 may emit infrared light. In some embodiments, the illumination apparatus 120 may be in communication with one or more components of the image acquisition system 100 (e.g., the image acquisition apparatus 110, the processor 130, or the storage device 150) via the network 140. In some embodiments, the illumination apparatus 120 may be directly connected with one or more components of the image acquisition system 100 (e.g., the image acquisition apparatus 110, the processor 130, or the storage device 150). In some embodiments, the illumination device 120 may be part of the image acquisition system 100. In some embodiments, the illumination device 120 may be an external device that communicates or does not communicate with the image acquisition system 100. In some embodiments, the illumination device 120 may be integrated with the image acquisition device 110 as a signaling device. In some embodiments, the illumination device 120 may be controlled by one or more components of the image acquisition system 100 (e.g., an exposure time controller of the image acquisition device 110, the processor 130). For example, the exposure time controller of the image acquisition device 110 may send an exposure time control signal to a switching device (e.g., an infrared filter) of the illumination device 120. The exposure time control signal may control the time of the operating state or the non-operating state of the switching device.

Processor 130 may process information and/or data to perform one or more functions described herein. For example, processor 130 may generate an enhanced image based on the color image data and the luminance image data.

In some embodiments, processor 130 may be a single server or a group of servers. The server groups may be centralized or distributed (e.g., processor 130 may be a distributed system). In some embodiments, the processor 130 may be local or remote. For example, the processor 130 may access or send information and/or data in the image acquisition apparatus 110, the lighting apparatus 120, or the storage device 150 via the network 140. As another example, the processor 130 may be directly connected to the image acquisition apparatus 110, the lighting apparatus 120, or the storage device 150 to access/transmit information and/or data. In some embodiments, the processor 130 may be implemented on a cloud platform. By way of example only, the cloud platform may include a private cloud, a public cloud, a hybrid cloud, a community cloud, a distributed cloud, an internal cloud, a multi-tiered cloud, and the like, or any combination thereof.

Accordingly, aspects of the methods of image processing and/or other processes as described herein may be embodied in programming. The procedural aspects of the technology may be considered an "article of manufacture" or an "article of manufacture," typically embodied or embodied in a machine-readable medium in the form of executable code and/or associated data. Tangible, non-transitory "storage" type media include any or all of memory or other storage for a computer, processor, or the like, or modules associated therewith, such as various semiconductor memories, tape drives, disk drives, etc., that may provide storage for software programming at any time.

All or portions of the software may sometimes communicate over a network, such as the internet or various other telecommunications networks. For example, such communication may enable loading of software from one computer or processor to another computer or processor, e.g., from a management server or host of the scheduling system into a hardware platform of a computing environment or other system implementing the computing environment or similar functionality related to image processing. Thus, another type of media that may carry software elements includes optical, electrical, and electromagnetic waves, such as used across physical interfaces between local devices, through wired and optical landline networks and through various air links. The physical elements carrying such waves, such as wired or wireless links, optical links, etc., may also be considered as media carrying software. As used herein, unless limited to a tangible "storage" medium, terms such as a computer or machine "readable medium" refer to any medium that participates in providing instructions to a processor for execution.

A machine-readable medium may take many forms, including but not limited to, tangible storage media, carrier wave media, or physical transmission media. Non-volatile storage media include, for example, optical or magnetic disks, any storage device in any computer, etc., which may be used to implement the system shown in the figures or any component thereof. Volatile storage media may include dynamic memory, such as the main memory of such a computer platform. Tangible transmission media may include coaxial cables; copper wire and fiber optics, including the wires that form the bus in a computer system. Carrier-wave transmission media can take the form of electrical or electromagnetic signals, or acoustic or light waves, such as those generated during Radio Frequency (RF) and Infrared (IR) data communications. Common forms of computer-readable media may include, for example: a floppy disk, a flexible disk, hard disk, magnetic tape, any other magnetic medium, a CD-ROM, DVD or DVD-ROM, any other optical medium, punch cards paper tape, any other physical storage medium with patterns of holes, a RAM, a PROM, and EPROM, a FLASH-EPROM, any other memory chip or cartridge, a carrier wave transporting data or instructions, cables or links transporting such a carrier wave, or any other medium from which a computer can read programming code and/or data. Many forms of these computer-readable media may be involved in carrying one or more sequences of one or more instructions to a physical processor for execution.

Those skilled in the art will recognize that the present teachings may be subject to various modifications and/or enhancements. For example, although implementations of the various components described herein may be implemented in a hardware device, they may also be implemented as a software-only solution (e.g., installation on an existing server). Further, image processing as disclosed herein may be implemented as firmware, a firmware/software combination, a firmware/hardware combination, or a hardware/firmware/software combination.

FIG. 4 is a schematic diagram of an exemplary processor, shown in accordance with some embodiments of the present description. The processor 130 may include an image acquisition module 410, a control module 420, and an image processing module 430.

Image acquisition module 410 may be configured to acquire images from image acquisition device 110. For example, the image acquisition module 410 may acquire the first image under a visible light source emitted by the illumination device. The first image may include color information. As another example, the image acquisition module 410 may acquire the second image under an infrared light source emitted by the illumination device. The second image may include luminance information. In some embodiments, the image acquisition module 410 may acquire images from the storage device 150 (or any other memory of the image acquisition system 100).

The control module 420 may be configured to control one or more components of the image acquisition system 100 (e.g., the image acquisition device 110, the lighting device 120, etc.). For example, the control module 420 may control the image acquisition device 110 to acquire an image. As another example, the control module 420 may control the lighting device 120 to automatically switch between the visible light source and the infrared light source. For example, the control module 420 may be a timing control module that controls a time for turning on or off an infrared filter of the lighting device 120. As another example, the control module 420 may be in communication with a photosensor. In response to the ambient light around the lighting device 120 detected by the photo sensor being weak light, the control module 420 may issue a driving signal for driving the infrared filter to the non-operating state. The lighting device may emit visible light. In response to the light sensor detecting that the intensity of the ambient light surrounding the lighting device 120 is intense light, the control module 420 may issue a drive signal for driving the infrared filter to the non-operating state. The lighting device may emit visible light. In response to the light sensor detecting the weak light intensity of the ambient light around the lighting device 120, the control module 420 may emit a driving signal for driving the infrared filter to an operating state. The lighting device may emit infrared light.

The image processing module 430 may be configured to process the image acquired by the image acquisition module 410. For example, the image processing module 430 may fuse a first image including color information and a second image including luminance information to generate an enhanced image.

The modules in the processor 130 may be connected or in communication with each other via a wired connection or a wireless connection. The wired connection may include a metal cable, an optical cable, a hybrid cable, and the like, or any combination thereof. The wireless connection may include a Local Area Network (LAN), a Wide Area Network (WAN), bluetooth, zigbee network, Near Field Communication (NFC), etc., or any combination thereof. Two or more modules may be combined into a single module. Any of the modules may be divided into two or more units. For example, the image acquisition module 410 and the image processing module 430 may be combined into a single module, which may acquire and process image data. As another example, the control module 420 may be integrated into the lighting device 120 instead of the processor 130.

A cap packing (also referred to as a second sealing member) 550 may be disposed between the cap part (also referred to as a second cover plate) 513 and the lamp socket 510, and the lamp socket 510 is made of a waterproof high temperature resistant material such as silicone. The cover sealing ring (also referred to as a second seal) 550 may be configured to seal the lamp holder. The cover part (also referred to as a second cover plate) 513 may be detachably coupled with the lamp socket 510. A cover part (also referred to as a second cover plate) 513 may be configured to cover the lamp socket 510. A lid gasket (also referred to as a second seal) 550 may cooperate with the lid (also referred to as a second cover) 513 to prevent water (e.g., rain) from entering the interior of the lighting device 120.

The driving assembly may have a square housing integrally connected with the outside of the lamp socket 510. The interior space of the square housing may be configured to mount a motor component (also referred to as a motor) 570. The motor portion (also referred to as a motor) 570 may be configured to provide power to the drive assembly. For example, the motor portion (also referred to as motor) 570 may be controlled to rotate in different directions (e.g., clockwise or counterclockwise), which may determine the state (e.g., operating state or non-operating state) of the infrared filter portion (also referred to as filter) 511. A motor seal (also referred to as a first seal) 560 may be disposed between the motor portion (also referred to as a motor) 570 and the motor cover plate (also referred to as a first cover plate) 580 to seal the motor. For example, the motor seal ring (also referred to as a first seal) 560 may be configured to reduce vibrations generated by operation of the motor component (also referred to as a motor) 570. In some embodiments, the motor seal ring (also referred to as a first seal) 560 may be made of a waterproof material and may cooperate with the motor cover plate (also referred to as a first cover plate) 580 to prevent water from entering the motor components (also referred to as the motor) 570. The motor cover plate (also referred to as a first cover plate) 580 may be configured to cover the motor part (also referred to as a motor) 570. The optical coupler 590 may be configured to determine the state of the infrared filter portion (also referred to as a filter) 511.

The infrared filter portion (also referred to as a filter) 511 may be configured to filter visible light from light emitted from the lamp bead (also referred to as a light source) 540 and pass infrared light when it is in an operating state. When the infrared filter portion (also referred to as filter) 511 is in a non-operational state, light emitted by the lamp bead (also referred to as light source) 540 can pass through unimpeded. Two pressing plates (also referred to as first pressing plates) 512-1 and 512-2 may be disposed between the infrared filter part (also referred to as a filter) 511 and the cover part (also referred to as a second cover plate) 513 to fix the infrared filter part (also referred to as a filter) 511 to the lamp socket 510.

It should be noted that the foregoing description is provided for the purpose of illustration only, and is not intended to limit the scope of the present specification. Various changes and modifications to the embodiments described herein will be apparent to those skilled in the art. However, such changes and modifications do not depart from the scope of the present specification. For example, the driving assembly may be disposed at the bottom of the lamp socket 510. As another example, the driving assembly may be directly disposed within the lamp socket 510.

Fig. 6 illustrates an exemplary cross-sectional side view of a lighting device according to some embodiments of the present description. As shown in fig. 6, the drive assembly (also referred to as a drive module) may further include a drive rod 610 and a stop device 640. The cover portion (also referred to as a second cover plate) 513 may further include a pressing plate (also referred to as a second pressing plate) 620 and a glass cover 630. The drive rod 610 may be connected to a motor portion (also referred to as a motor) 570 and rotates in synchronization with the motor portion (also referred to as a motor) 570.

For example, the rotation angle of the motor part (also referred to as motor) 570 may be limited to an angular range of 0 to 95 degrees. The glass cover 630 may be configured to protect the lighting device 120. For example, the glass cover 630 may prevent water and dust from entering the lighting device 120 and allow light emitted by the light bead (also referred to as light source) 540 to exit to illuminate an object. A pressing plate (also referred to as a second pressing plate) 620 may be provided on the outside of the glass cover 630 to fix the glass cover 630 to the lamp socket 510.

In some embodiments, the lamp holder 510 may have an approximately cup-shaped structure. An isolator (also referred to as a spacer) 520 and a lamp bead (also referred to as a light source) 540 may be sequentially disposed at the bottom of the cup-shaped lamp holder 510. The light reflecting portion (also referred to as a light reflecting cup) 530 may be nested in the lamp base 510, having a similar approximately cup-shaped configuration, but smaller in size. Holes entering the lamp beads (also referred to as light sources) 540 inside the reflecting part (also referred to as a reflecting cup) 530 may be designed at the bottom of the reflecting part (also referred to as a reflecting cup) 530, so that the reflecting part (also referred to as a reflecting cup) 530 may concentrate the light emitted by the lamp beads (also referred to as light sources).

As shown in fig. 6, the driving assembly may be disposed at an outer side near the top of the lamp socket 510. The square housing of the drive assembly may provide an interior space for a motor portion (also referred to as motor) 570, the motor portion (also referred to as motor) 570 being connected to an infrared filter portion (also referred to as filter) 511. A motor sealing ring (also referred to as a first sealing member) 560 and a motor cover plate (also referred to as a first cover plate) 580 may be sequentially disposed outside the motor part (also referred to as a motor) 570 to seal the motor part, for example, from rain, dew, dust, fog, or the like, or any combination thereof. The limiting device 640 may be connected to the motor part (also referred to as a motor) 570 to limit the rotation angle of the motor part (also referred to as a motor) 570.

In fig. 6, an infrared filter portion (also referred to as a filter) 511 may be placed within the socket 510 near the top and over the lamp bead (also referred to as a light source) 540 to filter out light emitted by the lamp bead (also referred to as a light source) 540. The infrared filter part (also referred to as a filter) 511 may be connected to the motor part (also referred to as a motor) 570, and switches its operating state according to the rotation angle of the motor part (also referred to as a motor) 570. In some embodiments, the infrared filter part may include at least two blades. The driving lever 610 may be connected to an infrared filter part (also referred to as a filter) 511 and serves to maintain the same rotation angle of the blades of the infrared filter part (also referred to as a filter) 511. At the top of the lamp socket 510, a cover part (also referred to as a second cover plate) 513 including a pressing plate (also referred to as a second pressing plate) 620 and a glass cover 630 may be detachably coupled to the lamp socket 510. The detachable connection may include a snap connection, a screw connection, a hinge connection, or the like, or any combination thereof.

It should be noted that the foregoing description is provided for the purpose of illustration only, and is not intended to limit the scope of the present specification. Various changes and modifications to the embodiments described herein will be apparent to those skilled in the art. However, such changes and modifications do not depart from the scope of the present specification. For example, the limiting means 640 may not be connected to the motor part (also referred to as motor) 570, but may be integrally or detachably connected to the infrared filter part (also referred to as filter) 511. In this case, when the infrared filter part (also referred to as a filter) 511 is driven to rotate by the motor part (also referred to as a motor) 570, the stopper 640 may be rotated in synchronization.

Fig. 7A and 7B are side views, respectively, of an exemplary infrared filter according to some embodiments of the present description.

As shown in fig. 7A and 7B, the infrared filter may include at least two blades (a master blade 710, one or more slave blades 720), a plurality of connection shafts 730, and a driving lever 610. Each of the at least two blades may be an infrared filter that may absorb visible light but allow infrared light to pass through. Each of the at least two blades may correspond to one rotation shaft of the at least two connection shafts 730 and a connection part through which the blade may be connected with the driving lever 610. In some embodiments, the main blade 710 may be removably coupled with a motor assembly (also referred to as a motor) 570. When the motor rotates at a certain angle, the main blade 710 may be rotated at the same angle by being driven by the motor. Rotation of the main blade 710 may drive the drive rod 610 through the connection. The movement of the drive rod 610 may also drive the one or more slave blades 720 to synchronously rotate at the same respective angles through the respective connecting members of the one or more slave blades 720 and the connecting shaft 730.

In fig. 7A and 7B, two different operating states of the infrared filter portion (also referred to as filter) 511 can be shown. The infrared filter portion (also referred to as a filter) 511 may be in a non-operating state as shown in fig. 7A and in an operating state as shown in fig. 7B. The at least two blades may be erected when the infrared filter portion (also referred to as filter) 511 is in a non-operating state. Light emitted by the light bead (also referred to as a light source) 540, including visible light and infrared light, may be directed onto an object (e.g., a license plate, a driver's face, etc.). The at least two blades may be lowered when the infrared filter part (also referred to as filter) 511 is in operation. Visible light in the light emitted by the light bead (also referred to as light source) 540 can be absorbed. Meanwhile, the infrared light can pass through and irradiate on an object (such as a license plate, the face of a driver and the like).

It should be noted that the foregoing description is provided for the purpose of illustration only, and is not intended to limit the scope of the present specification. Various changes and modifications to the embodiments described herein will be apparent to those skilled in the art. However, such changes and modifications do not depart from the scope of the present specification. For example, a motor portion (also referred to as a motor) 570 may be coupled to the drive rod 610. Thus, rotation of the motor may directly drive the drive rod 610 to move further, thereby causing rotation of the at least two blades. As another example, for each of the at least two blades, a motor may be provided to control the rotation thereof.

FIG. 8 illustrates an exemplary primary blade according to some embodiments herein.

As shown in fig. 8, the main blade 710 may include an optocoupler shutter 810, a groove 820, a shutter shaft 830, and a connecting shaft 840. The optocoupler shutter 810 may be detachably connected to one end of the shutter shaft 830 and may rotate synchronously with the main blade 710. The optocoupler baffle 810 can be used to determine the angle of rotation of the main blade 710 based on determining whether the optocoupler signal is blocked by the optocoupler baffle 810. More description of the optocoupler baffle 810 can be found elsewhere in this specification (e.g., fig. 11B and 12B and their description).

The grooves 820 may be configured to connect a motor portion (also referred to as a motor) 570 to the main blade 710 such that the motor and main blade rotate in synchronization. The cross-sectional view of the grooves 820 may be letters (e.g., "D", "T", "C", etc.), characters (e.g., "-", "+", "═ θ", "Φ", etc.), polygons (e.g., triangles, squares, rectangles, diamonds, hexagons, etc.), or the like, or any combination thereof. In some embodiments, the groove 820 may have a plurality of cross-sectional views corresponding to different depths. For example, the groove 820 may have two different cross-sectional views, such as "x" and "□". The depth of the groove 820 may range from 0 to 5 millimeters. The "x" shaped cross-sectional view of the groove 820 may correspond to a depth range of 3-5 millimeters. The "□" shaped cross-sectional view of the groove 820 may correspond to a depth range of 0-3 millimeters.

The damper shaft 830 may be mounted on a motor portion (also referred to as a motor) 570. The damper shaft 830 may be part of the main blade 710. The damper shaft 830 may be located at the top or bottom of the main blade 710. The main blade 710 may rotate about the flap shaft 830 in a clockwise/counterclockwise direction. In some embodiments, when the main blade 710 is erected, it may correspond to a non-operational state of the infrared filter portion (also referred to as filter) 511. When the main blade 710 is lowered, it may correspond to the operating state of the infrared filter part (also referred to as filter) 511.

The connecting shaft 840 may be connected to the driving rod 610 and configured to drive the driving rod 610 to move when the main blade 710 is driven to rotate by the motor part (also referred to as a motor) 570.

It should be noted that the foregoing description is provided for the purpose of illustration only, and is not intended to limit the scope of the present specification. Various changes and modifications to the embodiments described herein will be apparent to those skilled in the art. However, such changes and modifications do not depart from the scope of the present specification. For example, optocoupler baffle 810 can be integrally or removably coupled with stop 640. In this case, optocoupler bezel 810 may rotate in synchronization with stop 640. As another example, the optocoupler baffle 810 may be fixed to the lamp socket 510 and the optocoupler 590 may be integrally or removably connected with the stop 640 or the baffle shaft 830.

Fig. 10 illustrates an exemplary assembly of an infrared filter and a motor according to some embodiments of the present description.

As shown in fig. 10, a motor portion (also referred to as a motor) 570 may rotate in direction 1. The main blade 710 can be driven to rotate in direction 2 due to the connection between the motor portion (also referred to as motor) 570 and the shutter shaft 830 via the grooves 820. For the connection between the main blade 710 and the driving lever 610 through the connection shaft 840, the driving lever 610 may be driven to move in the direction 3. Further, movement of the drive rod 610 may drive the slave blade 720 to rotate in direction 4. In some embodiments, direction 1, direction 2, and direction 4 may be the same (e.g., clockwise). The direction 3 may be a direction parallel to the driving rod 610.

It should be noted that the foregoing description is provided for the purpose of illustration only, and is not intended to limit the scope of the present specification. Various changes and modifications to the embodiments described herein will be apparent to those skilled in the art. However, such changes and modifications do not depart from the scope of the present specification. For example, the motor portion (also referred to as motor) 570 may rotate in a clockwise direction. The master blade 710 and the slave blade 720 may be synchronously driven to rotate in a clockwise direction.

Fig. 11A is a partial side view of an exemplary lighting device according to some embodiments of the present description. Fig. 11B is a partially enlarged side view of an exemplary lighting device according to some embodiments of the present description.

As shown in fig. 11A, when the infrared filter part (also referred to as a filter) 511 is in an operating state, the blades (the master blade 710 and the slave blade 720) of the infrared filter part (also referred to as a filter) 511 can be laid down. In this case, the light emitted by the lamp bead (also referred to as light source) 540 may be filtered. Fig. 11B shows the position information of the limiting means 640 and the optocoupler shutter 810 when the infrared filter part (also referred to as filter) 511 is in operation. As shown in fig. 11B, the stopper 640 rotates rightward. The optocoupler shutter 810 is in a position to block the optocoupler signal.

Fig. 12A is a partial side view of an exemplary lighting device according to some embodiments of the present description. Fig. 12B is a partially enlarged side view of an exemplary lighting device according to some embodiments of the present description.

As shown in fig. 12A, when the infrared filter part (also referred to as a filter) 511 is in a non-operating state, the infrared filter part (also referred to as a filter) 511 blades (the master blade 710 and the slave blade 720) may be erected. In this case, light emitted by the lamp bead (also referred to as light source) 540 may be allowed to pass. Fig. 11B shows position information of the limiting means 640 and the photo-coupler shutter 810 when the infrared filter part (also referred to as filter) 511 is in a non-operating state. As shown in fig. 11B, the stopper 640 rotates leftward. The optocoupler shutter 810 is in a position that may not block the optocoupler signal.

In some embodiments, the initial position of the blade may be determined based on determining whether the optocoupler signal is blocked. For example, in case 1, a blade having an inclination angle greater than 0 degrees but less than 90 degrees may be shown in fig. 11A and 11B. The optocoupler signal can be blocked by the optocoupler baffle 810. Processor 130 may receive the state of optical coupler 590 and may control the motor to rotate counterclockwise until the optical coupler signal is not blocked by optical coupler stop 810 on motor hinge 1110. Further, the processor 130 may record the position of the blade as an initial position. In case 2, the blade inclined at an angle greater than 90 degrees is as shown in fig. 12A and 12B. The optocoupler signal may not be blocked by the optocoupler baffle 810. The processor 130 may control the motor to rotate clockwise by a certain angle (e.g., 30 degrees), which may cause the optocoupler signal to be blocked. At this point, returning to case 1, the processor 130 may further look up and record the initial position of the blade. After the initial position of the blade is determined, the rotation of the infrared filter part (also referred to as a filter) 511 can be controlled by controlling the step angle of the stepping motor according to the determination of whether it is daytime.

In some embodiments, the illumination device 120 may also include a photosensor. The photosensor may be used to detect ambient light around the lighting device 120. In some embodiments, the lighting device 120 may also include a processor in communication with the sensor and the drive assembly (also referred to as a drive module). The processor may determine the light intensity of the ambient light detected by the light sensor. Based on determining that the light intensity is greater than the intensity threshold, the processor 130 may control the motor to remain in the initial position (operating state). Based on determining that the light intensity is less than the intensity threshold, the processor 130 may control the motor to rotate 90 degrees from the initial position (non-operating state). After the abnormal power outage is restarted, the apparatus may determine an initial position according to the above-described method and then perform a subsequent operation according to information detected by the photosensor.

In some embodiments, the lighting device 120 may also include a timing control module. The timing control module may be configured to control the time for turning on or off the infrared portion (also referred to as filter) 511. For example, the timing control module may turn the infrared filter on to the on state at every preset time (e.g., 18:00 pm every day). As another example, the timing control module may turn off the infrared filter to the non-operating state at every preset time (e.g., 8:00 a.m. every day).

It should be noted that the foregoing description is provided for the purpose of illustration only, and is not intended to limit the scope of the present specification. Various changes and modifications to the embodiments described herein will be apparent to those skilled in the art. However, such changes and modifications do not depart from the scope of the present specification.

Fig. 13A is a top view of an exemplary infrared filter according to some embodiments of the present description. Fig. 13B is a top view of an exemplary infrared filter according to some embodiments of the present description.

As shown in fig. 13A, the infrared filter part (also referred to as a filter) 511 may include at least two blades. For example, the infrared filter part may include a master blade 1310 and one or more slave blades. The at least two blades may be driven by a drive module, such as at least two gears. Each of the at least two gears may be mounted on each of the at least two blades. The motor may drive the main blade 1310 to rotate at an angle via a gear corresponding to the main blade 1310. Through the gear of the blade, one or more slave blades can be synchronously driven to rotate at the same angle.

As shown in FIG. 13B, an infrared filter portion (also referred to as a filter) 511 may include at least two vanes 1330 and a rotating ring 1340. Each of the at least two vanes may include a drive rod 1350 and a baffle shaft 1370. Rotating ring 1340 may be connected to at least two blades by at least two drive arcs 1360 (as a drive module). Each of the at least two drive arcs 1360 may correspond to one drive rod 1350 of a blade. When the motor rotates, the rotating ring 1340 can be driven to rotate synchronously. Additionally, drive rods 1350 may be driven to move along their respective drive arcs 1360. When the driving arc 1360 is driven in a downward direction, the infrared filter portion (also referred to as a filter) 511 may be in a non-operating state to cause the lighting device 120 to emit visible light. When the driving arc 1360 is driven to an upward direction (a direction parallel to the baffle axis 1370), the infrared filter portion (also referred to as a filter) 511 may be in an operating state to cause the lighting device 120 to emit infrared light.

It should be noted that the foregoing description is provided for the purpose of illustration only, and is not intended to limit the scope of the present specification. Various changes and modifications to the embodiments described herein will be apparent to those skilled in the art. However, such changes and modifications do not depart from the scope of the present specification. For example, a drive rod corresponding to the drive arc may be provided in the main blade. The slave blade may be driven by a drive rod that is connected to the master blade and the slave blade.

Returning to fig. 1, the processor 130 may acquire a first image under a visible light source emitted by the illumination device 120 and a second image under an infrared light source emitted by the illumination device 120. In some embodiments, the first image may include color information and the second image may include brightness information. In some embodiments, processor 130 may generate an enhanced image based on the first image and the second image. For example, the processor 130 may fuse color information in the first image and luminance information in the second image to generate an enhanced image. In some embodiments, the enhanced image may be a color image with enhanced brightness. In this way, elements in the captured image can be easily identified in dark environments, such as at night or under backlight conditions.
